CONCRETE-CASING Application led December To all wlw/m, it f'ncy concern# Be it known that 1, CHARLES H. LAssrrnR,

a citizen or United States, residing at Valv entine, in the county ot Jett Bavis and State of Texas, have invented new and useful Impiovements in Concrete-Casing-b/llaking Machines, of which the following is a specification.

This invention relates to well machinery and has tor its object the provision of a novel device by means of which a.concrete lining may be applied within a. well to form a casing therefor, regardless ot the type of well. v v

An important object is the provision `of a device of this character which is formed as a concrete or cement mixer and also as a distributor for placing the mixed material'within the well at any desired location therein, means being furthermore provided whereby this lining may be smoothed on".

Another object is the provision of a device ot this character which includes means whereby the agitating or mining member may be raised or lowered and also including means whereby the agitating or mixing member may be rotated, means being provided whereby the di'erent movements may be accomplished lwhen desired.

A further object is the provision ot a device of this character which will be simple and inexpensive in manufacture, highly efficient in use, durable in service, and a general improvement in the art.

W' ith the above and other objects and advantages in view, the invention consists in the details of constructionA to be hereinafter more fully described and claimed and illustrated in the accompanying'drawings in which- 'I y Figure 1 is a side elevation of my device in applied position within a well,`

Figure 2 is a view taken 'at right angles to Figure 1,

Figure 3 is a longitudinal sectional view through the mechanism disposed within the well,

Figure l is a cross sectional view therethrough on the line 41-41 of Figure 3,

Figure 5 is a cross sectional view on the line 5 5 of Figure 3, showing the expansible bottom in contracted position,

Figure' is a similarview showing the eX- pansible member in its other position,

Figure 8 is a horizontal sectional' lView therethrough, and

The remaining ligures are detail views. Referring more particularly to the drawings, the numeral 10 designates a barrel of cylindrical or slightly oval form adapted for insertion within a well formed at its lower end with a bearing 11. Threadedly con- Anected with the upper end ot' this barrel 10 is a reducing nipple 12 which is provided l .with portsl 13 and from which leads an up-` wardly extending reduced extension 14 leading up through thetop of the well and through a platform 15 disposed above the `top thereof.

Located within the barrel 10 is a mixing cylinder 16A which is cylindrical in form and which is spaced from thecbarrel 10 so asto provide an annular space 17 between these two members. At itslower. end the cylindrical member lis provided with a bearing 18 engaging and rotatable upon the bearing 11. Located within the cylindrical member 16 is a central shaft 19 provided at its lower end with a squared end 2O and having secured thereon intermediate. its ends an auger-like conveyor or lagitator .member 21.

Disposed a-t the lower ends of the barrel 1() and mixing member, 16 is any eirpansible head or bottomv closure including a pair of substantially semi-circular disks 22 slidable upon the guide disk 23 and having' a relatively large opening 24llwithl which communicate vlateral openings 25 extending vto the peripheries of the disks 22 .and 23. The disk 22 carries a plurality ot laterally movable members 2(5 which have extensions 27 to which are lconnected coil' springs 28 which 1in turnl connected' with a head portion 29 termed on the'disk-22. rThis hub portion is formed with a rectangular socket 30 engageableby the squaredend20`ot the shaft 19. .This construction constitutes in effect an eXpansible cam member which is so constructed that when the hub member 29 and consequently the disk members 22 are rotated relatively to the disk 23, an eX- pansible action of the members 26 :will be effected so as to move them into engagement with the lwall of the well. Secured upon the lower portion of the shaft 19 is a .plate27 likewise formed as a disk and 'ormingthe lower end tor the conveyor or agitator 21.

The shaft 19 extends a. considerable distance above the platform 15 at the top of the 3. A device of the character described comprising a barrel, means for rotating said barrel, a cylinder within the barrel, a shaft rotatable within said cylinder and carrying a spiral blade constituting a combined agitator and conveyor, a disk on the lower end of the shaft fitting within the cylinder said barrel being provided with openings above the upper end of the conveyor blades, a head rotatably mounted at the lower end of the barrel and cylinder, means for moving said shaft longitudinally whereby to bring its lower end into and out of drive connection with said head, a gear threaded upon said shaft and means for rotating said gears in one direction or the other whereby to effect said longitudinal movement of the shaft.

et. A device of the character described comprising a barrel, means for rotating said barrel, a cylinder within said barrel, a shaft rotatable within said cylinder carrying a disk closing the cylinder, a combined agitator and conveyor carried by said shaft, said barrel being provided above said conveyor with openings, a cutter head engageable by the lower end of said shaft whereby to be driven thereby, means for rotating said shaft, and other means for effecting longitudinal movement thereof whereby to cause engagement or disengagement with the cutter head and to raise the disk for eX- pelling the contents of the cylinder.

5. A device of the character described comprising a barrel, means for rotating said barrel, a cylinder within said barrel, a shaft rotatable within said cylinder carrying a disk forming a closure for the lower end of the cylinder, a combined agitator and conveyor'blades carried by said shaft, said barrel being provided above said conveyor with openings, a cutter head mounted at the lower end of said shaft, the upper end of said barrel and cylinder being threaded, a gear adapted to be selectively clamped for rotation with or adjusted for rotation upon said shaft, said gear being threadedly engaged with said shaft, and means for rotating said gear whereby to raise and lowei1 the shaft for making or breaking the drive connection with the cutter head, and means for raising said disk whereby to expel the contents of the cylinder.

6. A device of the character described comprising al barrel, means for rotating said barrel, a cylinder within said barrel, a shaft rotatable within said cylinder carrying a disk forming a closure for the lower end of the cylinder, a spiral blade constituting va combined agitator and conveyor carried by said shaft, said barrel being provided above said conveyor with openings, a cutter head mounted at the lower end of said barrel and cylinder, the upper end of said shaft being threaded, `a gear threaded upon said'shaft, means for locking said gear rigid with respect to said shaft, whereby to raise and lower the cylinder into and out of drive relation to the cutter head, and means for rotating said gear in either direction, the upward movement of the shaft resulting in moving the disk upwardly whereby to expel the contents of the cylinder.

7. A device of the character described comprising a barrel, a cylinder rotatably mounted within the barrel, gear operated means for rotating the cylinder, a cutter head rotatably mounted at the lower end of the cylinder' and barrel and formed with an angular socket, a shaft rotatably mounted within the cylinder, a'disk at the lower end of said shaft forming a closure for the cylinder, the lower end of said shaft bein' formed with an angular extension adapted for engagement within said socket, the upper end of said shaft being threaded, a member threadedly engaged upon the upper end of said shaft, a ring gear rotatably mounted with respect to said member, means for driving said gear in either direction, and locking means associated with said gear and said member whereby to lock the tube for rotation as one.

In testimony whereof I afliX mysignature.
